On the outer si e of the ventilator ubber strips may be secured at thev edges of I provide a series of Screened portions 15, l16, 1 preferably semi-crcular` in form, or ng, to aid in producing a" movement of t e air currents furnished to the car.` 5 A A.. tri ar shaped casing 14f`may.. be attached y means of'felamp' `plates orl flanges 14 and 14b and bolts :or srews 14, to the casing'l at the forward end','"and this auxiliary casing lforms, 'with compartment 2, a. funnel shaped forward entrance tothe ventilator casing.l The attachable casing 14 ,is rovidd with-a front screen 14d and outf si e screen 14, and' at the forward end of the casin I locate a fan or windwheel 18,

i5 supporte on shaft 25 which is journaled in beari'n s 26. l v

At t e front of casing 1 a sprocket wheel 22 is supported on-the shaft 19 and rotatable'therewith. This wheel is connected by sprocket chain,A 23 to a second sprocket wheel 24 rotatable with the shaft 25 which is -supported inijournal bearings or brackets 26. At its rear end the driven shaft carries a bevel gear 27,'-wl1ich meshes with a' 25 similar ear 28 secured on the stud shaft 29,

, which s a'ft also carries the automatically reversible Ventilating fan 30. This fan 3U is located in the compartment 4, back of the protective 4screen 6, which latter is ofV strong wireija'vith a comparatively large mesh to permit, entrance of air currents, but which .forms an effective barriera ainst accidents due to contact with the revolving fan. The shaft and gearing are inclosed by a metallic i casin 31 secured at the outer side of the venti ator box. The ventilatin fan. is of peculiar construction, its vanes eing automatically movable to adapt it to use with the vcar when the car is reversed in its di- 40 rection of travel, as will be described hereinafter more lfully.

When properly adjusted in position and the train is running, the motion of the car causes the forward fan or windwheel 18 to rotate, as will be understood. The action of the revolving fan or wheel dis els the lyin cinders from the proximity oi) the forwar screens and prevents their entrance throughy the ventilator, thus eliminating the passage 50 of cind'ers, grit, etc. to the interior of the car. The rotation of the wind `wheel or fan also revolves the ventilator fan 30, and the action of this fan causes the air currents to be set in motion, and said currents are irnpelled through the'screencd door ofthe casing 1 into the interior of the car; the screens forming an effective barrier against entrance of cinders etc., and the fan provides a sup- 4 ply of fresh air at lall times to the moving 6o car.

e.; As illustrated in Figs. 1 to-5, the mechanl f ism of the device may be propelled by actuating means as shown. This actuating means com rises an lactuating fan 32 supportedV o nY shaft '33 on the roof of the car; vel gears 'as heretofore described. Y, i

'I` l l'. l ted respectively on shaftBS `and short shaft 36; a second pair of'beveligears '37'y and'38 carried respectively by shafts 3G andI 39; and' a third pairof bevel ears 40 and 41 rotatable with shafts 39and aft 19. 70

In operation of this device, the motion of.

the movlng train causes the air currents to revolve the wind wheel or fan-32 on the car' roof, and power-is transmitted through the connections described-to the driven shaft, which in turn rotates the Ventilating fan 30,

To provide for travel of the carin reverse directlon and .-eliminate'gthe objectionable I feature ofl'inanually alte'rn the Ventilating -30 fan to adapt it for its wor I, fan 30 is provided with automatically movable vanos 42.` Each of these vanes Iis pivotedat 43 to a hub 44, which hub" is rectangular `in cross section, and the end 45 of the vanel is in- '85 closed between the forked end 46 of a screw bolt 47. The bolt 47 is secured in a vsleeve'48V on the shaft 29, and its forked end projects through a slot 49 formed radially of the hub. It will thus be observed that the vane'v 90 may swing or swivel on its pivot to a limited extent, and as 'itswings the forked boltscause the sleeve to revolve until the bolts strike the walls of thel slots of the hubs, and the revolving motion is thus 'transmitted 95 from the vanes of the wheel or fan to. the.

'shaft 29. It will `he evident that u on 'aret'he vanes willswing on. their pivotsunti they are properly setto receive the impact from the passing air` currents; f
